On the test you should know:
  • How to calculate density of regular and irregular objects
  • Manipulate the density equation to solve for mass, or volume.
  • Know the Steps of the Scientific Method.
  • Be able to identify Independent Variable, and Dependent Variable.

Videos & Notes

  • Understanding the Units of Density
  • How to Manipulate Equations (Important!)
  • How to Solve Density Problems
  • Density of Irregularly Shaped Objects
    • Calculate the mass in grams with the triple beam balance
      • Calculate to the nearest hundredth (estimate between the lines)
        • Example 234.43 g
    • Calculate the volume in mL by displacement in a graduated cylinder (dropping things in water)
      • Put an amount of water in a graduated cylinder that will submerge the object completely
      • Note the original volume
      • Drop the object in
      • Note the new volume (take the reading from the bottom of the meniscus )
      • Calculate to the nearest tenth (estimate between the lines)
        • Example 43.3 mL
    • D=m/v
      • (unit is g/mL)
      • Round to 2 decimals)





























  • Density of Regularly Shaped Objects
    • Calculate the mass the same as before
    • Calculate the volume using the equation LxWxH
      • Measure in cm
      • Calculate to the nearest tenth (estimate between the lines)
  • Example 9.4 cm
    • Calculate the density the same as before
